GoPago offers a $10 GoPago credit for free when you download GoPago for iOS, Android, or Blackberry, via coupon code "TheTruth". (You will be prompted to enter the code during the registration process.) That's the first such promotion we've seen from GoPago, an app that allows you to browse, order, and pay for goods and services on your smartphone. The credit is good at participating stores in the San Francisco Bay area and Las Vegas. Credit expires July 21.
